Back in May, fans of CBS's "How I Met Your Mother" finally learned the identity of the titular mama: Cherry Hill's own Cristin Milioti, who was at that point known for her Tony Award-nominated performance in the Broadway musical "Once."

When Milioti auditioned for the part, she didn't even know she was up for the part of the Mother. "I kind of put it together because it was so secretive," Milioti said.

"I had to sign a Russian novel of confidentiality agreements." 

"Neil Patrick Harris [who plays notorious lothario-turned-groom-to-be Barney Stinson] congratulated me by accident. I flew out to film that finale the day after I finished 'Once.' It was in a out-of-body, white-hot excitement," Milioti said. "I felt like I was some sort of secret assassin."

Milioti said that since she was revealed as the mother, fans have been coming up to her and welcoming her to the fold, even giving her unprompted hugs.

Milioti also told me that she recently joked with a "HIMYM" writer about how she spent her time in Philly as a kid. "Where else would a 15-year-old go to walk around, wear hemp necklaces and be angry but South Street?" she said.

The ninth season of "How I Met Your Mother" starts tonight on CBS at 8 p.m.
